ASTM A240 Type 304H is widely utilized austenitic stainless steel, modified with controlled carbon content to enhance its strength at temperatures up to 1500°F (816°C). It is common practice for SS 304H Plate to be dual certified as 304H and 304H. The higher carbon content of 304H enables it to meet the mechanical properties and grain size requirements of 304H. Alloy 304H Plate exhibits excellent corrosion resistance similar to 304H/304H L, resisting atmospheric corrosion as well as oxidizing and reducing environments.
